Another option you may want to look at is: Competition Electronics ProChrono
Competition Electronics ProChrono Digital Chronograph
I have been very pleased with mine.
in that price range all I can think of is Shooting Chrony, and they have reviews all over the board, some people think they are great chronys for the money, some people hate them. I'm in the same position you are, looking for a chrony
I don't think a 'decent' chronograph can be purchased for $100-$120. Unless 'decent' means nothing more than confirmation that a bullet passed over the unit.
If you intend to use the recorded velocities for any serious purpose, you'll have to pay more.
